BRICK-'SCORING ArrAnA'rUs.

Apimeauon mei reti-any 12, 1925,` 'serial N. 8,776'. Renewed' his invention relatiesV to apparatus for scoring wire cut brick to'yform ,iat is. coinmonly termed rough teXtur'e7 bricks.V 'Heretofore the uncut brick has been scored by the use of a plate having a plurality' of scratchcrs carried thereon so that they may be adjusted relatire to one another to tend to maintain the scorings of even depths. The above device requires careful watching and attention as the thickness of the brick inateriai varies due to swelling and contraction of the brick material after it leaves the brick machine and this causes the depths of the scorings to vary. My object is to devise apparatus which will overcome these difiiculties and which is simple and cheap to manuI facture yet durable and efficient.

l attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which- Fig. 1 isa sectional view of a brick machine showing part of my scoring apparatus in use therewith;

Fig. 2 a cross-section, on the line Fig. 1, on a larger scale;

Fig. a perspective view of part ofthe column of brick material after it has been scored;

Fig. 4 a perspective view of a brick showing its position when in use;

Fig. 5 a plan view of the scoring device shown in Fig. 1, on a larger scale;

Fig. 6 a detail of one of the upper scratching elements; and

Fig. 7 a detail of one of the side scratching elements.

1 is a machine adapted material through a die 2. The width of the die is equal to the length of the bricks to be made while its height is equal to the width of a brick. By transversely cutting the column, as indicated. by the dotted line a in Fig. 3, bricks are formed. This cutting operato eXtrude brick tion is usually edected by wires, not shown,.

the wires being spaced apart a distance equal to the desired thickness of the brick. The upper surface or top 3 of the column forms the exposed or outer surface of a brick when it is in use and the sides 4 of the kcolumn form the ends of the brick, these ends, of course, are not always exposed. As the column of material is extruded from the die Q; it slides across a plate 5, which is in alinernent with the lower edge of the die, and

passes'o'n to a conveyor 6 which carries it to the vcuttingr apparatus. V

vThe plate 5 may be supported in position by a' frame' 7 which is extended abovethe upper surface of the column and is provided with transverse and longitudinal members 7a and 7b. A plurality of rods. 3a, carried by the longitudinal members 7b, are transversely arranged above the upper surface 3 of the column. On each of these rods are pivoted a plurality of scratching members comprising lingers 31 and prongs 3c. Each finger is provided with a hole adapted to receive a prong which is releasably carried therein by means of a set screw 8. These scratching members are arranged on the rods in staggered relationship so that the desired number of scorings or grooves may be made by the prongs in the surface of the brick material as it passes under the prongs.

By varying the pressure of the prongs against the brick material the depths of the grooves may be varied. This is accomplished by providing a weight or weights 9 at the free end of each finger so that it is an easy matter to make a change when a different depthed groove is required. These weights may be releasably held in place on the fingers by passing them over studs carried on the fingers and provided with wing nuts 10 for engagement with the weights.

vTo score the sides 4 of the brick material 1 provide the longitudinal rods 4a suitably carried by the frame 7 and arranged at each side 4. On these rods 4a are pivoted a plurality of depending fingers 4b, each having a laterally extending prong 4"'. These prongs are removably carried in any suitable manner on the fingers and are pressed by means of weights 11 against the sides 4. The weights are slidably carried on laterally extending arms 12 carried by the fingers so they may be shifted towards or away from the latter vto vary the pressure of the prongs. Set screws 13 are provided to lock the weights as adjusted. The prongs 4c are vertically spaced apart so that each forms a mark in the brick material.

From the above description it is obvious that the width of the spaces between the scorings may be doubled by throwing alternate scratching members out of action. These members may be held in their ino erative position by any suitable means. t is also evident that should one of the scratching members not work properly by digging in too deep or by forming too shallow a groove, none of the other scratchers will be affected and the trouble may be readily fixed by changing the pressure of the prong against the surface of the column.

What I claim is l. Apparatus for scoring brick comprising a plurality oi' independent scoring members floating-ly supported relative to the surface of the brick material; and individe ual means for yieldingly pressing each scoring member towards the brick.

2. Apparatus for scoring brick comprising a plurality of independent scoring memreses/i7 bers floatingly supported relative to the sure face ot the brick material and arranged in a plurality of rows in different positions lengthwise of the brick material; and individual means for yieldingly pressing each scoring member towards the brick.

3. Apparatus ior scoring brickconiprising a plurality of rods; a plurality of i'ingers v pivoted on each rod; a prong carried by each ringer for scoring a surface of the brick Inaterial; and means for independently varying the pressure oteach prong.
